This is something I keep struggling with.

If someone wants to vibe code an alternative to a SaaS tool, my gut feeling is "no, this is bad and it will blow up" as vibe-coded projects tend to do.

But then the alternative is often paying $X million per year for licenses to a half-assed program that hasn't had a UI update since 2005.

I just don't have a good argument on why they shouldn't when the outcome will be just as dogshit, only cheaper and flashier.
